An analytical system that enlarges the specific capabilities of two basic analytical methods now provides f a s t and positive answers to difficult analytical problems. Here's how i t works : The Perkin-Elmer Model 154-C Vapor Fractome t e r — a new gas chromatographic instrument —first separates the sample into relatively pure fractions, recorded fractograms providing the quantitative information. Trie fractions are collected, and then run through the P-E Inf racord,® a new low-cost ($3,850), compact, double-beam, bench spectrophotometer. Here, infrared analysis supplies the detailed qualitative data difficult to
